Resin-modified glass-ionomers and conventional glass-ionomer cements release significantly more fluoride than composites and compomers. Fluoride release decreased over time for all tested dental restorative materials.

Area of Science:

  • Dental Materials Science
  • Biomaterials Engineering
  • Restorative Dentistry

Background:

  • Dental restorative materials are crucial for tooth repair.
  • Fluoride release from restorative materials can offer carioprotective benefits.
  • Understanding fluoride release patterns is essential for material selection.

Purpose of the Study:

  • To evaluate and compare fluoride release from various light-activated dental restorative materials.
  • To compare fluoride release with a conventional glass-ionomer cement.
  • To analyze the rate and amount of fluoride release over time.

Main Methods:

  • Fluoride release was measured from resin-modified glass-ionomers, composites, and compomers.
  • Materials were light-activated before testing.

  • Comparison was made against a conventional acid-base glass-ionomer cement.

    • Main Results:

    • Significant differences in fluoride release were observed among material types (p < 0.05).
    • Resin-modified glass-ionomers and conventional glass-ionomer cements showed higher fluoride release than composites and compomers.
    • Composites released less fluoride than compomers.
    • Fluoride release significantly decreased across all tested time intervals for all materials.

    Conclusions:

    • Material type significantly influences fluoride release in dental restoratives.
    • Glass-ionomer based materials demonstrate superior fluoride-releasing potential compared to composites and compomers.
    • The observed decrease in fluoride release suggests a finite reservoir or altered diffusion over time.
